Can some one please give me inside info on acquiring a boat slip or cabin in July??? Understand everything booked for Native preference!

Hard to believe you can't find anything out that way. Check your sources, I think they are incorrect. The place is usually empty. Check the Forks Chamber of commerce for hotels etc.. Or just stay at Mora campground. Don't know if its Bob's place or not, but we got burned at 3 Rivers last year. We had arranged for a late check out, then got charged another night when someone else was running the desk. We won't stay there again, ever. Too bad, it was convenient.

Maybe one of these will lead you in the right direction.
